Golf IV / Jetta IV :: Car Idle For About A Half Hour And Shuts Off
Sep 8, 2013
I have narrowed down my starting issue to a faulty relay(409). When I pulled the relay and cleaned the contacts and reinstalled the pump primed and the car started. Car will idle for about a 1/2 hour and out of the blue it shuts off. If I try to restart, 9 times out of 10 it does not start. If i tap the relay, it starts right up. If the car is running and I tap on the relay the car stutters and if I tap it again it shuts off.

This happens not all the time, can cold start and the car runs fine but then once its shut off then started for use again later it will shut down, sit on roadside for 2 minutes with key off and then restart and good to go again...its a random thing...the check engine light does come on...

I noticed through careful investigation that my 03 GTI 1.8T (180,000 KM's or 111,850 miles) will grind 3rd when in these conditions:
1. When the car has been driving for more then half an hour and everything is hot
2. When the car is over 2800 RPM's while hot (ie. getting on a highway)
Now I know lot's of people blame syncro's and yes I could see that my car has had 8 previous owners so I can't say they all shifted perfect. But what I do know is that when I downshift from either 4th or Neutral it will never grind even when I don't Rev Match or "Blip" the throttle. So it can't be syncro's in my opinion.
So what I've done to the car to rule out some problems were:
- Change the gear oil from what ever it was before to Royal Purple 75W-90 (NO luck.)
- Then I added a short shifter and adjusted my cables properly (still No luck)
- Finally I noticed my shifter was sloppy and one of my bushings were torn so I bought 42 DD's metal bushings and the shifter did stiffen up a lot, however!!! (No luck)
I know it's not my driving technique because I watch my foot depress the clutch fully and then I gently push it into third. I also know I'm shifting correctly because I can double clutch and normally shift through every other gear properly without any grinds or clunks. Just the devilish 3rd gear.
I would like to hear the solution. I'm going to change the oil one more time to Redline MT-90 and see how that goes, but if that doesn't work I might just tear apart or get a new tranny.

I searched but couldn't immediately find anything about this particular line. I've been struggling with a rough idle for the past couple weeks, throwing codes that I'm running to lean all the time. I cleaned the throttle body and MAF, and was in the process of replacing the MAF and noticed a small hose fitting behind the MAF but before the throttle body was pretty much split in half. I don't know what it's for and I'm replacing it regardless, but could this be the source of my problem?

Just replaced the starter and battery on my old but loved 4Runner. I drove it for an hour and a half last week and couldn't restart it. Just nothing - one click I think. A friend tapped on the starter and it started...but I'm not sure whether the car just cooled down at that point. Took it to the garage and they said they couldn't find anything wrong (no surprise, right?) Now I'm afraid to take longer trips.

My GC is overheating. Started as occasionally but now increasing in frequency. I find it will being to overheat after driving on the interstate for half hour or so but I can "calm" it back down but turning on the heat. I've replaced the following:
1. coolant (no drips or leaks nor am I losing coolant over time)
2. thermostat (twice)
3. temperature sensor
4. serpentine belt and tensioner
5. radiator (last summer)
6. water pump (last winter)
I notice the fans run more often than they should. For example, after a 10 minute ride to work in the morning,. I notice the fans are running as I pull into my parking space.

I have been having a brake drag problem with my '89 Jeep Wrangler. I posted this problem previously when I thought it was an E-brake issue. I did a rear drum spring set change. The problem persisted, so I asked the local auto parts store and they said it could be a faulty master cylinder which I just replaced. The brakes felt fine for the first 1/2 hour driving, then the pedal started feeling harder to push and the brakes were dragging again. I jacked the car up and removed the tires to find both front calipers tight on the rotor, the rears would spin. With someone pressing the pedal, I did not notice any caliper movement.

I've had this checked out twice by the dealer and once by another mechanic and they say there's nothing wrong ....
First symptom: the heater will start out hot but about a half-hour into my trip into work it significantly cools down. I'm not sure if it's starting out too hot and cooling down appropriately but I think not ... it gets downright cool at 70 degrees.
Second symptom: I sometimes smell coolant in the passenger compartment, usually while I'm operating the heater. However, in these last bitter cold days I've smelled it when I get into my cold car in the garage in the morning.
Third symptom: I have a film on the inside of my windshield on the lower one-sixth or so ... it gets very cloudy, particularly when I circulate air to the windshield or turn on the AC to defog. I've asked three times to have the heater core checked and they all say it's fine.

I have a 2003 rav4 with about 100000 miles on it. Over the last 4 months I have noticed that, whenever I drive half hour or longer on the highway the car starts to smell like burning rubber or burning antifreeze or something like that. I live close to work, play, and groceries, so I don't drive it that long very often. I have not noticed decreased levels of any of my fluids. No change in performance either. I've had the oil changed regularly and no problems there. I am about to drive it a thousand plus miles and would love to get this figured out before I go.

After one hour of freeway speed (60-80) the car slows down to a stop and red !triangle! light comes on. After coasting to the shoulder and waiting 10 minutes, car restarts. This has happened 3 times in the last two months (very frightening, but luckily it was light traffic). Dealer says 'no codes' and that there is nothing to fix!!!! What now? I can't drive a car that could lose power at any moment. Big safety issue....

I have a 2001 vw jetta 2.0 and I was accelerating on the interstate the other day and the car just started bogging down and now the car only accelerates slowly at partial throttle any more and it makes a loud intake noise and bogs down also the car idles bad and even at partial throttle the car struggles to get above 3k rpm, I scan for codes and got MAF, O2 sensor before the cat and camshaft position sensor, I replaced the camshaft position sensor and car still runs like crap, what is the problem??

Symptoms:
- rough start-up, car shuts down
- backfire when releasing after WOT
- OBD-II codes (see below)
Okay so these issues started to appear only 1 day after I got tuned...
Problem History:
Day 1:
- car started mildly rough
- I got an EPC light on my dash 2 minutes after moving and for 2 seconds the car sounded like an STI (the sound you hear with a misfire)
- I turned it off and on, EPC gone car started up normally
- took it straight to dealer, they checked coils and plugs and said that it's a tune issue.
- went to take it back from the dealer and that was the first time the car shutdown immediately after start-up. it started at second attempt with a quite long ignition sound and the STI-like sound briefly once again.
Day 2:
- I went to my friend and we pulled the codes from OBD-II and only got the P0420 00 [175] - Efficiency Below Threshold code only (as the dealer probably erased any other code related to my EPC light)
- we deleted the code and drove around
- every time we turn the car off and on. The car starts up mildly rough and the code comes back up
Every 2 days or so:
- the car would require 2 attempts to start but no EPC light coming up.
Day 4:
- I had a night of possibly 6 WOTs to test the cars performance, and it was performing great. didn't feel any loss in power or anything. (was friendly racing my friends modded 135i with very impressive outcomes)
- car backfires after i release the gas pedal at WOT (not with every WOT but 2 out of 6 runs it backfired)
- After the last WOT i got the EPC light. turned the car off and let her relax for 5 minutes.
- car took 2 attempts to startup. with severe roughness and shakes (as if the car is cammed V8 engine) for 5 seconds and then back to normal.
Now since the EPC light came back on i wanted to check if there is another code from the OBD-II. I was hoping that the issue will only be the P0420 00 [175] - Efficiency Below Threshold code but my fears were true and i got another very annoying code
This is last nights code pull
2 Faults Found:
14914 - Boost Pressure Regulation
P0299 00 [096] - Control Range Not Reached
Intermittent - Not Confirmed - Tested Since Memory Clear
[Code] .....
Day 7:
- The car had the sever start-up roughness again
As I'm trying to find a solution for my problem here are the steps i took/will take:
- took it to the dealer for nothing.
- ordered an O2 sensor extender for the P0420 00 [175] - Efficiency Below Threshold code and i hope it's somewhat related to the start-up issue. it will arrive today or tomorrow.
- once the extender is here, I'll take it to an exhaust shop to install the extender and check for any DP/Exhaust leaks
- I will take it to a mechanic to check any leaks in all intake/air connectors and piping, any leaks in DV (I have forge recirculating DV), Boost pressure sensors (the piggy back was connected to them and one might be loose when we removed it), spark plugs and coils.

I have a 2005 jetta 2.0 Once it gets under half a tank I lose power, it acts like it's running out of gas. It only does it in warmer weather (this started in march when we took it to Florida, once it got back in the cold weather it didn't do it again until 2 days ago when it was in the 70's). I took it to he mechanic I've used since I got the car (he works exclusively on vw and audis). It didn't do it to him in the two weeks he had it, he couldn't find anything wrong that would cause the issue.
He did do a complete tune up, replaced both of my fans and coolant. I ended up replacing the coolant temp sensor myself since that decided to go bad after I got it back. It lost power after getting the car back again warm weather and just under half a tank of gas. Prior to the Florida trip the water pump, timing belt and starter were replaced. I had my fuel pump replaced in 2014. It is an automatic with 157k miles on it.

Symptoms:
1. As I'm coming to a stop the rpms drop to about 4-500 and the battery light comes on.
2. But instead of shutting off the car revs itself to about 1.5k and does this about 2 or 3 times. (bouncing between 500 and 1.5k rpms.)
3. Car then either settles at a normal idle, or it turns off.
This happens when I'm coming to a stop in neutral or 1st with the clutch pressed down. If I come to a stop in 2nd gear with the clutch down it either does nothing, or just 1 and 2 but doesn't shut off.

Throwing the following codes:
p2401- evap emission system leak detection pump control circuit low
p0261- cyl 1 injector circuit low
p0267- cyl 3 "
p0270- cyl 4 "
p0264- cyl 2 "
p0445- evap emission system purge control valve circuit shorted
p2257- secondary air injection system control A circuit low
p0010- A camshaft position actuator/open bank 1
p0414- secondary air injection system switching valve A circuit shorted
Obviously an electrical issue, no way all these codes spring up all at once for separate reasons. Any fuses, relays, harnesses or grounds that relate to all or most of these problems.
Car has trouble at start up, takes a little longer to turn over. If I don't stay on the gas it will eventually cut off. Once I am driving its fine. Its only once the E brake is up, it will cut off right after the brake light comes on.

I have a 2.0 Avh jetta. Around January I started getting intermittent cel coming up. I pulled the code back then and it said it was misfiring cylinders. It'd give me some rough idling when it was on. Since then the light would come on during wet weather. About a week ago the light came on and stayed on. I haven't been able to pull a code recently though to see if it is the same as before (cant get vcds to connect to my car for some reason).
My car has randomly died with a battery light (electronics stay on, engine shuts off) and I know this is pretty dangerous but it hasn't happened on a main road. I replaced the coilpack yesterday and planned to change the spark plugs as well but the spark plugs turned out to be more than i was equipped for (i do have them). Since I replaced the coilpack the car no longer rough idles but it did shut off with the battery light coming on. I'm really trying to avoid taking it in somewhere but I'm starting to think that is my only option left.
Should also add that the car starts up just fine initially but after a random battery light shut off it is a hard start and sometimes takes a few tries...

I got a mkv R32 with 57k miles (DSG transmission) on it and the past few weeks ive been having some crazy issues. My car shuts off once in awhile when I come to a stop in traffic or at red lights. Last night it happen again I came to a red light and the car shut off, when I restarted it my idle was bouncing all over the place all the way up to 2500rpm and down to 1300rpm. Also, in addition to the idle every time i started pressing the gas the car would KICK like something was wrong with the transmission and a CEL came on. I ran the codes and it said MAF was at fault and I have had a MAF code again maybe a month ago.
I am thinking of replacing the MAF to see if it fixes the problem and I was wondering if it is a straight hardware swap or will i need to do some programming with a vag com?

i have a 03 gti vr6. 24v 6 speed. it started losing coolant the other day. but the thing is the radiator all the hoses and the water pump(s) are all dry. its fine when its cold, holds coolant just fine. but when it warms up its only fine at idle, so im guessing its some sort of pressure related leak. the car goes through half a gallon every mile or so. only the inner fender on the left side is soaked and the suspension components on that side as well.

When I parked this car 2 months ago it ran fine. Went to start it up and it starts and shuts down. I do not think its the security issue. Both keys do the same thing.
Battery is new recently. There are no MIL lights working on the dash except the battery light. The actual dash lights will not come on. Doors will unlock but not lock. My VAG tester will not communicate with the ECU.
I have checked all of the fuses multiple times. I can hear the fuel pump prime up when the key is turned on. It appears that there is an electrical issue. I took the connections off of the ecu, waited a bit, check for cleanliness and reinstalled also.

My issue is on my 1999 Vw Golf MK4 2.0 L Automatic is that today I was heading home from my Moms house. I noticed a fuel smell coming from the engine . I was making a turn to head west then the car suddenly turned off while still in motion.. I let the car die completely turned it back on and it eventually turned back on .The check engine light was on I then headed home I also noticed while in 4-5 RPM the car would not have that much pressure . Like it wanted to shut off again .. I was doing some research from similar issues like mine . Someone said to replace my EGR Valve and my Speed sensor.
